Assume that the external arrivals are Poisson (inter-arrival times exponentially distributed), all service times are exponentially distributed, all routing is probabilistic, and all queues have infinite length Questions 1. [30 points] Compute by hand the effective arrival rate for server S5. Attach your computations, and make sure that they are legible [20 points] Solve the queueing network and give the results in the table below. For this question you can use a spreadsheet, the mmc.exe program, or do it by and 2. Number (L) Time (W) Station S1 S2 S3 Utilization (p) S4 S5 S6 System
